The music is pretty cool - you go around the maps and in certain places they have little music symbols and if you click on it, it opens a play list appropriate to that area. So the one by Star Tours brings up a Star Wars music playlist, for example. If you do the one near the entrance to the park it is sort of a medley of songs for that park
Where are you seeing the music symbols? I have an Android and all I see are the trivia and attraction game icons.
